01

The InRak™ is a high performance in-row

cooling solution which precisely cools

and conditions air in close proximity to

the servers and provides industry-leading

cooling for its footprint.

Advanced air flow management within the InRak™ innovatively transmits cooled air horizontally across the front of the server racks. This acts as a curtain, providing even cooling over the full height of the server rack whilst managing the aisle static pressure. Single circuit models of the InRak™ are available in DX or chilled water (CW) units and dual circuit in CW.

Flexible, scalable application

The compact, modular InRak™ is an ideal solution for:

The InRak™ can be positioned next to a single rack; within a row of six 10kW server cabinets for example or sit between two 30kW racks in a higher density area.

The InRak™ can be integrated into a traditional hot or cold aisle system, but when applied with aisle containment, the performance of the InRak™ is significantly enhanced. In hot aisle containment, the fans draw in hot air rejected by the servers. Due to the minimum distance that the hot air has to travel, the risk of cold air mixing with rejected hot air is greatly decreased. This in turn reduces the need for low supply air temperatures, enabling the data centre to operate at higher temperature, which improves efficiency.

Integration with a free-cooling chiller

Chilled water models of the InRak™ deliver even greater efficiency when integrated with one or more Airedale free-cooling chillers. Free-cooling saves vast amounts of energy, particularly when room temperatures are high. For free-cooling to operate, the temperature difference between the ambient air and return water can be as little as 1°C.

Concurrent free-cooling

Airedale chillers offer concurrent free-cooling which enables free-cooling to be captured whenever the ambient is below the return water temperature. The system controls constantly monitor the temperature differences and will only switch on the mechanically-driven compressor when extra cooling is needed, introducing concurrent free-cooling - a mixture of free-cooling and mechanical cooling.

A higher water supply temperature of up to 17°C raises the free-cooling threshold of all Airedalefree-cooling chillers including the more compact variants. When an Airedale free-cooling chiller is linked with the InRak™ in a 24/7 data centre with a typical room temperature of 24°C, free-cooling will be active for more than 95% of the year (London, UK).

The control centre of each of our cooling systems is a sophisticated electronic microprocessor with control logic specially developed by Airedale.

The microprocessor uses sensors to send and receive messages to and from active components such as compressors, fans and pumps so they interact with each other, balancing cooling duty, temperature, air flow and pressure to exactly match the application.

By integrating intelligent components, the controller manages and optimises the system’s performance and reduces power draw.

Smart networking solutions:

Fully-programmable via the control panel’s user-friendly display, the microprocessor can be linked with all standard BMS protocols to:

24/7 total confidence

Resilience is designed into InRak™ units from day one and is managed by advanced controls logic to give you complete confidence that your data centre is never put at risk and to help you achieve data centre tier classification.

N+1 fans

The InRak’s four fans run up to 75% capacity during normal operation. If one fan fails, the other three fans instantly speed up to 100% if required, to provide the same total amount of cooling and maintain temperature control. They then modulate back when a fourth fan is in operation again. All fans are ‘hot swappable’ as standard.

Pressure differential management

The InRak™ maintains pressure in the aisle containment system within the server design envelope, whilst still ensuring temperature is controlled.

Automatic transfer switch

In the event of a power failure, power supply is switched instantly to an alternative power supply and cooling continues, supporting redundancy power supply specifications in critical data centre builds.

Hot swappable fan management

Each of the unit’s centrifugal fans are ‘hot swappable’ allowing the fan assembly to be replaced while the unit is still running.

Future-proof, flexible, 24/7

As an intelligent stand-alone unit or when networked with up to eight units, the InRak™ adapts to your data centre’s particular requirement. Its compact, modular design makes it easy for multiple units of different size and capacity to be added as load increases or to eliminate hot spots. Smartly networked standby units ensure 24/7 availability.

As you grow your data centre

Designed to be stand-alone, Airedale units are even more efficient when integrated together, sharing intelligence and reducing your total lifecycle costs. Our systems give you the confidence to move from low to medium to high density cooling as you populate and grow your data centre – from small rooms with DX indoor units linked with condensers outside to larger rooms benefitting from the better heat transfer of chilled water coupled with a free-cooling chiller.

InRak™ DX – cooling by compressor

InRak™ DX is part of a closed refrigerant circuit controlled by scroll compressor technology. The InRak™ fans draw hot return air across an evaporator, heat is transferred into the refrigerant and dispelled via an external air cooled condenser.

InRak™ CW - chilled water cooling

In a closed chilled water circuit, fans in the InRak™ CW pull hot return air across the heat exchanger, transferring heat to the cooling water, fed to a chiller located externally which removes the heat and returns chilled water back to the InRak.

The challenge

Egton Medical Information Systems Ltd (EMIS) is the UK’s leading supplier of healthcare software and related services to GP practices and is estimated to hold the data for around 39 million patient records. EMIS required a new 24/7 data centre as expansion to the existing facility in order to increase its secure and resilient capacity. The data centre incorporates a highly efficient, reliable cooling and monitoring solution designed by Airedale.

Airedale solution

The InRak™ units make the aisle containment far more efficient; they are very clever; they communicate with each other to maintain pressure and temperature consistent with the room. Their EC fans are great – they are all linked to the ACIS™ and ramp up and down according to demand. ACIS™ gives us 24/7 control of the operation and peace of mind. When the data centre is fully populated, the Airedale cooling solution should guarantee an annualised PUE of 1.3 for the room.
